Law Java/4M ,6 Q1. 08 04 0 A): d/dmw y/i 2 I esaees fore the electrode7) is cast/upon it, is covered with the thinnest possible layer ofsolder. A close connection of the electrodes a and h is thus effected,and a firm support for the lat ter is also provided 7 The connection ofthe electrodes of the adjoining elements with one another is effected bymeans of. strong bridge-pieces d made of good eonductin g metaldi'fficult to melt. This bridge-piece is mad as follows: The pointedends ot both electrodes are covered for about ten millimeters withthethinnest possible layer of solder, and the connecting bridgepiece isthen cast over them, a close connection of the bridge with the ends'ofthe eleeto a miniinum.

' from one another byinsnlating layers 11. By

this arran geinent the fragile electrode 1) comes "between the strongparts of the projection 9* and the bridge (I and is therefore entirelyprotected both above and below and has a con The elements are separatedtinuous and extremely-firm support. The easily-melted metal of thefragile electrode is protected from too greata heat by the hard baseprojection. v

Having now particularly described and ascertained the nature of the saidinvention and in What manner the same is to be performed, I declare thatwhat I claim is r 1. In therlno-electric"batteries or piles thecombination of two solid staff-shaped electrodes in each element, one ofthem resting on a projection of the other, essentially as described.

2. In thermo-eleetrical batteries or piles the combination of astrongmetallic bridgepiece con meeting two adjoining elements with theforked ends of the electrodes.

In witness whereofh have hereunto set my hand in presence of twowitnesses.
